Please see images at Unity editor is not only shutting down. It is freezing the whole system. Must use power off button behind screen to completely turn off to shut down and restart. MAC: Is it safe to go ahead and delete all the GiCache files?? I believe it could be to do with the temp files although I am nervous about which files to delete. There are is a "Temp" folder inside my project which is small. Although in my Mac Library/Caches there are a whole bunch of Unity com.unity3d.UnityEditor / GiCache Folders and files Starting from 00, 0a,0b all the way up to fd, fe, ff. I am nervous to delete anything as I have a bunch of games almost finished, even though the Assets and Project Settings folders are backed up. Is it safe to go ahead and delete all the GiCache files??
